The library, which is located at the foot of the McKinley National Memorial, is owned and operated by the Stark County Historical Society, and located in Canton, Ohio, where McKinley built his career as lawyer, prosecuting attorney, congressman, governor and president.

The museum contains the largest collection of McKinley artifacts in the world and chronicles the life and career of the 25th president, from his birth to his death at the hands of an assassin.

Another exhibit also explores the construction of the Memorial and the unfortunate fate of the McKinleys' Canton home, destroyed by fire in 1937.

The Hoover-Price Planetarium was built during 1962, opened in July 1963, and stands adjacent to the McKinley National Memorial in Canton, Ohio.

The presidential archive itself is called the "Ramsayer Research Library" and is located in the South Wing of the building.
